Is IAS overvalued in 2026?
Integral Ad Science Holding LLC (IAS) currently trades at $10.34 per share with a market capitalization of $1,735,616,000.00. Based on our multi-factor framework, the stock appears richly valued with a Smart Value Score of 42/100. This score blends growth quality, financial health, and price attractiveness into a single institutional-grade read.
The stock trades at a P/E ratio of 36.9x, below its 5-year median of 45.4x.
Looking at its own history, IAS is currently trading cheaper than 67% of the last 5Y on P/E. This places it in the 33th percentile of its historical range, a reasonable but unremarkable position.
Our discounted cash flow model estimates IAS's intrinsic value at $9.56 per share, against the current market price of $10.34. This implies a premium to fair value of -8.16%. The stock is priced close to its estimated fair value, offering limited upside without further operational improvement.
Financial quality is a concern. The Piotroski F-Score of 0/9 flags weakening fundamentals that deserve closer scrutiny before the valuation case can be fully trusted.
Bottom line: IAS appears richly valued on our framework, with a Smart Value Score of 42/100. At current levels the risk/reward is skewed against the buyer. A materially lower price or significant operational improvement would be needed to change the picture.
Frequently asked questions
Is IAS overvalued?
IAS scores 42/100 on our Smart Value Score (Grade D), a weak overall profile. On valuation specifically, the DCF puts intrinsic value below the current price, so the stock is expensive on cash flow today. The score reflects growth and quality carrying it, not a cheap entry point.
What is IAS's fair value?
Our DCF model estimates IAS's intrinsic value at $9.56 per share, versus the current price of $10.34, a margin of safety of -8.16%. Fair value is the present value of the cash flows we project the business to produce, so a price above it means the market is paying up for growth the model does not yet assume.
What P/E ratio does IAS trade at?
IAS trades at a P/E of 36.9x on trailing twelve-month earnings, against a 5-year median of 45.4x. P/E is what you pay per dollar of profit, and sitting below its own median means the stock is cheaper than usual relative to its earnings.
Is IAS a buy based on valuation?
Our Smart Value rating for IAS is Sell, from a Smart Value Score of 42/100 that blends growth, quality, and valuation. The profile skews cautious, and a better price or clearer operating improvement would strengthen the case. This is research to inform your decision, not personalized financial advice.
How does IAS's valuation compare to its history?
On P/E, IAS sits in the 33rd percentile of its own 5Y range, below its long-run median relative to where it has traded. A low percentile means today's multiple is near the bottom of its historical band.
What is IAS's Smart Value Score?
IAS's Smart Value Score is 42/100. It is a proprietary WallStSmart metric blending growth quality, financial health, and valuation into a single 0-100 read, and scores above 75 are rare, signaling strong multi-factor alignment.
